at91_nand question

[Atsushi Nemoto]

Hi.  Looking at at91_nand.c, I found that this driver does not
controls NCE signal during normal operations.  The driver only enables
NCE on at91_nand_probe() and disables NCE on at91_nand_remove().

Is this normal behavior?  I thought a nand driver should control NCE
signal on cmd_ctrl routine.  If the nand driver supported only one
chip, it can omit NCE control?

Though it seems work fine as is, I wonder keeping chipselect signal
low all the time is normal.
